If I use "defaults write com.blizzard.worldofwarcraft DesktopModeIsDefault 1" on Terminal, OS X will allow me to use 1920 x 1080 on WoW. The game will be blurry but if I get the screenshot and view it on 2560 x 1440, it will look OK.

UPDATE: I just want to say that using Dark ShestakUI is good for 2560 x 1440. Everything looks good in auto UIscale and for 0.711111111...

Shadows help in filling in the gaps. Thank you m2jest1c!

Shadows in Dark Shestak can sometimes bug out on larger resolutions (especially for nameplates) so I just disabled it. Seeing that it looked great, I went back to Shestak UI and changed the border_color. I'm also using 0.79999995231628.
